240

- Let's examine the series: 2, 6, 12, 48, 240, 1440, 10080.

- The pattern is multiplication by consecutive integers:

- 2 × 3 = 6

- 6 × 2 = 12

- 12 × 4 = 48

- 48 × 5 = 240

- 240 × 6 = 1440

- 1440 × 7 = 10080

- Observe that '6' seems out of pattern since it's multiplied by 3, not 2.

Correct Answer: Option:2, 6

- Removing '6' and using '4' would fit the sequence better.

- Adjusted sequence would then be: 2 × 2 = 4, 4 × 3 = 12, continuing the pattern.
